METAL WEATHER STRIP Filed Sept. 24, 1934 Patented Nov. 26, 1935 UNITEDSTATES PATENT OFFICE METAL WEATHER STRIP Oscar Dahl, Chicago, Ill.,assgnor to Gardner Wire Company, Chicago, Ill., a corporation ofIllinois 4 Claims.

This invention relates to a metal weather strip and concerns itselfprimarily with a structure comprising a female member and a cooperatingmale member.

The primary purpose -of this invention is to provide a female memberhaving a resilient tongue that always produces an efficient seal againstthe ingress of weather. The resilient tongue is preferably formedintegrally with the female-member and acts to automatically take up allwear between the two members.

The invention comprises the novel structure and combination of partshereinafter described 'and more particularly pointed out and dened inthe appended claims.

In the accompanying drawing, which illustrates a preferred form of thisinvention, and in which similar reference numerals refer to similarfeatures in the different views:

Figure 1 is a fragmentary transverse sectional View through a windowequipped with a metal weather strip involving this invention.

Figure 2 is a fragmentary transverse sectional view through the base ofa door structure equipped with the same metal weather strip.

Figure 3 is an enlarged elevational view of the female memberillustrating its application to a window.

Figure 4 is an enlarged transverse sectional View through the femalemember of the weather proofing structure.

Figure 5 is an enlarged fragmentary sectional View illustrating themanner in which the female member is attached to its support.

In the drawing, there is illustrated the pre ferredembodiment of thisinvention, but it will be understood that different variations may beresorted to. The female member which is designated by the reference Fpreferably consists of a single integral structure formed from resilientsheet metal which is stamped or formed to provide a hookshaped portionl, at one end portion. The sheet of metal is folded uponr itself at anintermediate point as indicated at 2, and this folded portion provides adouble thickness for attaching purposes. The other end portion 3extending from the folded portion 2 is bent upwardly and is ofsufficient length to extend,within the hooked portion l. The terminal ofthe hook shaped portion l is preferably crimped over as indicated at lto provide a stronger edge for a purpose that will later appear, and theupwardly extending portion 3, which is in the nature of a resilienttongue, has its terminal edge bent inengaging the crimped edge 4. Itwill be noted that the portion containing the hook shaped end slopesupwardly a slight degree from the folded portion and is adapted toyield.

The folded portion. 2 is provided with aper- 5 tures for receivingsecuring nails 8. It will be noted that a small aperture 6 is formed inthe top member of the fold 2 that is of sufficient size to receive theshank of the nail, while a much larger aperture 'l is formed in thebottom member l0 of said fold of a diameter substantially equal to thediameter of the head 8a of the nail. Consequently, it is possible indriving the nails to counter-sink portions of the outer member of thefold 2 in the apertures 'l as shown in Fig. 5, to 15 bring the heads 8flush with the outer surface of the weather strip.

The female member is adapted to be attached to one of two relativelymovable members. A male member 9 as shown in Fig. l, or the male member20 9a shown in Fig. 2 is adapted to be attached to the other member. InFig. 1 the relatively movable members are illustrated as upper and lowerwindow sashes respectively designated as I0 and Il. The female member Fis secured upon the 25 inner surface of the sash I0, while the malemember 9 is secured upon the inner surface of sash II. The male member 9is shown as a strip of metal folded upon itself to provide a loop l2adapted for entering the female member F and 30 depressing the resilientor spring tongue 3, which urges the male member against the outer wallof the hooked end to efficiently exclude the weather. When the sash Il)is lowered or the sash Il is elevated, the male member 9 will readily bewith- 35 drawn from the female member.

In Fig. 2, the male member 9a is shown as a solid metal threshold plateattached to a base member I3 which may be the base of a door frame orthe like. This metal plate has a downturned 40 end M and a rib I5 forsupporting the main portion slightly above the base. The part thatenters the female member projects beyond the rib I5 and above the base.The female member F is shown as attached to the bottom edge of a door I6so 45 that when the door is closed, the female member F will engage overthe male member 9a, the spring tongue 3 being yieldingly depressed forefficiently excluding the weather, as is apparent.

From the foregoing, it will be apparent that a 50 novel weather proongstructure between two relatively movable members has been invented, thatautomatically takes up all looseness or wear of the parts to effectivelyexclude the weather.

I am aware that many changes may be made 55V and numerous details ofconstruction may be varied through a wide range Without departing fromthe principles of this invention, and I therefore do not purposelimiting hte patent granted hereon otherwise than is necessitated by theprior art.

I claim as my invention:

1. In a weather proofing structure, a sheet metal member having a foldedattaching portion comprising a bottom ply and a top ply, the top plyhaving small apertures adapted for receiving the sh anks of attachingmembers and the bottom ply having larger apertures substantially thesize of the heads on the attaching members for the purpose set forth.

2. In a Weather proong structure, a sheet metal member having a two plyattaching portion provided with apertures for receiving securing means,said apertures being enlarged in one ply for counter-sinking portions ofthe other ply therein.

3. A metal weather strip comprising a resilient sheet metal memberhaving cooperating terminal portions diverging into overlapping portionsforming a top ply and a bottom ply, the top ply having small aperturesfor receiving the Shanks of attaching members and the bottom ply havinglarger apertures substantially the size of the heads on the attachingmembers for the purpose set forth,

4. A metal weather strip for excluding `the Weather between a pair ofmembers, comprising a resilient sheet metal plate folded intermediate apair of opposed edges, said folded portion being flattened for receivingsecuring means for attachment to one of said members, the parts of saidplate forward of said flattened portion extending at an angle to saidlast mentioned member, one of said parts having a hook-shaped end forengaging over the other member and the other part of said plateconstituting a resilient tongue eX- tending at an angle to the firstmentioned part and into said hook-shaped end.
